Corned Beef Hash Pie
Ingredients
- 1¾ cups all-purpose flour
- 1 tsp. kosher salt
- 1 tsp. sugar
- ½ cup plus 2 Tbsp. cold unsalted butter, cubed
- 2 to 4 Tbsp. cold lager beer or beef broth
POTATOES
- 2 medium red potatoes, cut into ¼-in. cubes
- ½ tsp. kosher salt
- 3 green onions, chopped
- 2 Tbsp. unsalted butter, cubed
- 1 Tbsp. stone-ground Dijon mustard
- ½ tsp. pepper
PIE
- ½ lb. thinly sliced corned beef
- ¼ lb. sliced provolone cheese
- 1 Tbsp. cold whole milk or heavy whipping cream
Directions
- Whisk flour, salt and sugar; cut in butter until the size of small peas. Gradually add beer, tossing with a fork until dough holds together when pressed. Shape into a disk; wrap in plastic. Refrigerate 1 hour or overnight.
-
Place potatoes and salt in a saucepan; add water to cover. Bring to a boil. Reduce heat; simmer, uncovered, until potatoes are crisp-tender, 6-8 minutes. Drain. Return to saucepan; add green onions, butter, mustard and pepper. Cook over medium heat, stirring frequently, until potatoes are tender, 6-8 minutes. Remove from heat; cool.
-
Roll dough between two pieces of waxed paper to a ⅛-in.-thick, 12-in.- diameter circle. Remove top piece of waxed paper; place a 9-in. pie plate upside down over pastry. Lifting with waxed paper, carefully invert pastry into plate. Remove waxed paper. Trim pastry to ½ in. beyond rim of plate; flute edge. Refrigerate 30 minutes.
-
Preheat oven to 400°. Prick bottom and sides of pastry with a fork; line with a double thickness of foil. Fill with pie weights or dried beans. Bake on a lower oven rack until edges are light golden brown, 15-20 minutes. Remove foil and weights; bake until bottom is golden brown, 3-6 minutes longer. Cool slightly.
-
To assemble the pie, layer half the corned beef, half the cheese and three-fourths of potato mixture in baked crust. Repeat corned beef and cheese layers; sprinkle with remaining potato mixture. Re-roll dough trimmings; use a heart-shaped cookie cutter to make shamrock petals and a knife to cut out a stem. Top pie. Brush dough trimmings with milk. Bake until crust and cheese are golden brown, 35-40 minutes.
